Depending on the phase of the moons of Nirn at birth, the khajiit are born with a specific form corresponding to the phase of the moons and are stuck with that form for their entire life.

Masser and Secunda, Nirn's moons, are attendant spirits of the mortal plane.

If regular gravitational rules are applied, we can expect Secunda to eventually, gradually be dislodged from Masser's gravitational pull and come thundering down to Nirn.

Or they'll turn true binary and repel Nirn 

@DovahKiinZaan

Either way, Nirn is screwed.
